Since the spinning speeds of the forebody and the afterbody of a dual-spinning projectile are different in the direction of the axis of the projectile, one degree of freedom (DOF) is added to the six-DOF rigid body dynamic model, which is used as a basis.
Oesophagus shorter than pharynx, intestinal bifurcation in posterior third of forebody; caeca septated, terminate at some distance from excretory vesicle.
Lastly, the dynamic pressure ratio determined using Equation (5) and the increase in the coefficient of forebody drag [DELTA][C.sub.Dpf]/[C.sub.Dp,solo] obtained from the empirical formula in Figure 9 are substituted into Equation (4) to determine the aerodynamic drag reduction rate [DRR.sub.2] of the second vehicle.
Expression (5) has been used for the laminar forebody and the flat plate concept (e.g., [15]) for the turbulent tail.
By drawing on the merits of the existing airplane configuration design philosophy, a novel forebody design methodology which by rotating and assembling two waverider-based surfaces is firstly introduced, and a body-wing-blending configuration with double flanking air inlets layout is also presented.
It differs, however, in that the gonads are not situated in the hindbody and the holdfast organ is not situated immediately posterior to the end of the forebody. Bisseru (1956) described three Neodiplostomum species from birds of prey from Africa as well as from the Nile crocodile (Bisseru 1957), but these were all adult specimens and could not be compared to the larval forms.
The ESSM has an 8-inch diameter forebody that tapers to a 10-inch diameter rocket motor.
where the control inputs are fuel-to-air ratio <p, elevator deflection [[delta].sub.e], and canard deflection [[delta].sub.c]; [bar.q], S, [z.sub.T], [bar.c], [M.sub.[infinity]] denote dynamic pressure, reference area, thrust moment arm, mean aerodynamic chord, and Mach number; [DELTA][[tau].sub.1] and [DELTA][[tau].sub.2] are the forebody turn angle and the aftbody vertex angle which are linear mapping of elastic states [[eta].sub.i].
A Bezier surface, defined by several bulb geometrical parameters, has been used to model the forebody and to allow the modifications.
Peering is a common behavior in orthopteroid insects, and consists of standing in one location while moving the head and forebody back and forth, usually laterally and horizontally, along a line transverse to a line between the insect and the distant object.
